Convert Between JSON and XML from XSLT

Two XPath extension functions are available as built-in Oxygen functions for converting between JSON and XML formats from an XSLT file:

• xs:string xml-to-json(xs:string jsonText) - Converts the input jsonText to XML, using the JSON to XML conversion tool provided by Oxygen XML Editor.

• xs:string json-to-xml(xs:string xmlText) - Converts the input xmlText to JSON, using the XML to JSON conversion tool provided by Oxygen XML Editor.

  Tip:

  These functions are available in the list of content completion proposals when editing XPath expressions in XSLT 3.0 (or later).

The namespace of the functions is: xmlns:oxy=http://www.oxygenxml.com/extension (content completion is available for the xmlns:oxy prefix).

Examples of XSLT files that perform a conversion:

XML to JSON

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"    
                xmlns:oxy="http://www.oxygenxml.com/extension" version="3.0">

    <xsl:output method="text" indent="false" omit-xml-declaration="true"/>
    <xsl:template match="/">
        <xsl:value-of select="oxy:xml-to-json(serialize(node()))"/>
    </xsl:template>
</xsl:stylesheet>

JSON to XML

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"    
                xmlns:oxy="http://www.oxygenxml.com/extension" version="3.0">

    <xsl:template match=".">
        <xsl:variable name="xmlContent" 
select="oxy:json-to-xml(serialize(., map { 'method' : 'json', 'indent' : true() }))"/>
        <xsl:value-of select="$xmlContent" disable-output-escaping="true"/>
    </xsl:template>
</xsl:stylesheet>
